目的观察持续冲洗负压引流技术在腹部外科应用的临床效果。方法回顾性分析2006年1月至2011年3月期间我院将自制双套管实施持续冲洗负压引流技术应用于172例腹部外科患者的临床资料。结果全部患者的消化道瘘均治愈，瘘道愈合的平均时间为36 d。治疗过程中，1例患者出现上消化道出血，另1例出现腹腔出血，无腹腔感染、皮肤破溃感染、脓毒症等并发症。结论采用持续冲洗负压引流的双套管制作简单，经济有效，在腹部外科中对术后肠瘘、出血、胆汁漏及感染的防治具有重要临床意义。
Objective To analyse the clinico-pathological characteristics of young patients with colorectal cancer. Methods From January 1980 to January 2000, among 1 030 patients with colorectal cancer admitted for surgical treatment, 143 (13.9%) patients were ＜35 years of age. The clinicopathological data of these young patients were reviewed and compared with those of patients in the other age groups. Results In this series of young patients, males were predominat. Most of them were with poorly differentiated (37.8%) and muco-cellular (29.6%) adenocarcinoma. The mast common gross morphology was infiltrating type (56.6%) and colloid carcinoma type (31.5%). The majority of patients (89.5%) were in Dukes stage B and stage C. Conclusion The prognosis of young patients with colorectal cancer surgically treated is worse, due to the fact that most of them are in late stage and their cancers are worse in differentiation. To increase the awareness of cancer in the young is important for early diagnosis and treatment and better prognosis.
